staging: gdm724x: use !x instead of x == NULL

Functions like devm_kzalloc, kmalloc_array, devm_ioremap,
usb_alloc_urb, alloc_netdev return NULL as a return value on failure.
Generally, When NULL represents failure, !x is commonly used.

This patch cleans up the tests on the results of these functions, thereby
using !x instead of x == NULL or NULL == x. This is done via following
coccinelle script:

|
 x = alloc_netdev(...);
)
 ...
- if(NULL == x)

Further we have used isomorphism characteristics of coccinelle to
indicate x == NULL and NULL == x are equivalent. This is done via

Parentheses removal were left to the script. However, there were some
cases that were handled manually. In addition, handling pointer casts
were done manually too because not all replacements generated by the
script were suitable. When pointer casts on function arguments were
in the form:
    <func>(...,(<type> *)&<expression>,...)

the replacements were discarded due to compilation warnings.
