qcacld-3.0: Replace typedef tCsrTimerInfo

Per the Linux coding style "mixed-case names are frowned upon" and
"so-called Hungarian notation [...] is brain damaged." One identifier
used extensively throughout the driver that violates both of these
tenants is "pMac." In order to be compliant with the Linux coding
style there is a campaign to rename all instances of this identifier.

One instance is the following field in typedef tCsrTimerInfo:
-       tpAniSirGlobal pMac;

In order to meet the needs of the campaign all that is really needed
is to rename this field and modify all accesses to this field. However
note that the Linux coding style also objects to typedefs except in a
few cases, and the use case for tCsrTimerInfo does not apply.
Therefore to address the larger problem replace the tCsrTimerInfo
typedef with an appropriately named struct with appropriately named
fields.
